Automatically updating the CRL for pfSense
ar flag

I want to be able to automatically update the certificate revocation list on a virtual pfSense server running OpenVPN. I don't want the certificate authority to be on the same vpn server, but if pfSense is not running the CA I am not sure how I could update the CRL in an automated way. Has anyone attempted this before?

So I got a little "advanced firewall usage" question in Win10.

I have a VPN running in a VPS with openvpn , running like a charm , and I wanted to filter all the networking of my endhost (in this case Win10) What I mean by filtering is to apply an strict policy of "BlockInbound,BlockOutbound" , so I can just add rules to allow the communication with my VPS to establish the VPN Tunnel , (so it will creat ...

Do I need Active Directory Certificate Services
us flag

I have an AD setup that apparently has a vulnerability related to the Certificate Services feature. Thinking back through the MS Server courses I've sat, I don't remember anything on it, so I dug about online and I'm leaning towards "no".

I do not generate certs in-house for anything - workstations are allowed to Self-Sign, and my parent org has steps to follow for generating cert requests local ...

How can I search across CloudWatch log groups on AWS?
za flag

I have a number of lambda functions which run my serverless backend. Something somewhere is misbehaving, and I need to bring up/search all the logs from a particular time — from all log groups, not just a single one, or a single stream.

Is there a good way to search across all log groups and all streams?

I have tried the console, but this insists on driving down from log groups (for lambda, these eq ...

IPv6 DHCP PD reply going to FORWARD rule in iptables firewall?
th flag

On my Fedora 34 Linux firewall/router box I noticed

  • that IPV6 DHCP PD requests are sent out fine.
  • that IPV6 DHCP PD replies do arrive on the wire
  • that the firewall kernel for some reason sends the DHCP PD reply in the FORWARD rule even though dhclient is local
  • that addresses in the packets were correct, match with DHCP-server and local firewall.

Details can be found at redhat.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
